Electronic tag capable of coupling to metal

摘要

An electronic tag capable of coupling to metal can be attached to the metallic surface of a product, and includes a substrate, a radiation body arranged on a surface of the substrate, a grounding body and a reference line. The grounding body is also arranged on the aforementioned surface and electrically connects to the radiation body. The reference line is arranged on the aforementioned surface and in the grounding body. While such electronic tag is attached to the metallic surface of a product, a portion of the grounding body, which is opposite to the radiation body, contacts with such metallic surface, so that the signal reading distance of such electronic tag can be broadened and extended in virtue of coupling such grounding body with such metallic surface to cause the grounding area to be enlarged. The extent of such contact shall not extend beyond such reference line.

主权项

1. An electronic tag capable of coupling to metal, the electronic tag being attached to a metallic surface of a product, the electronic tag comprising:
a substrate; a radiation body arranged on a surface of the substrate; a grounding body arranged on the surface of the substrate having the radiation body thereon, the grounding body electrically connecting to the radiation body, the grounding body being of rectangular window frame shape; and a reference line arranged on the surface of the substrate having the grounding body thereon, the reference line arranged within the rectangular window frame formed by the grounding body, wherein the grounding body has a gap on a lateral side thereof and the lateral side is vertical to the reference line, a distance between the gap and the radiation body is smaller than a distance between the reference line and the radiation body; wherein while the electronic tag is attached to the metallic surface of a product, a portion of the grounding body, which is opposite to the radiation body, contacts with the metallic surface, so that the signal reading distance of the electronic tag can be broadened and extended in virtue of coupling the grounding body with the metallic surface to cause the grounding area to be enlarged.
